UPDATE (7/7/2023): I just got an email back from TeePublic and they've removed the thief's account from their platform.

Hey everyone,

I haven't posted here in a long time, and I'm sad to say this isn't good news. I recently found out my artwork got stolen and is being sold on TeePublic on mugs, t-shirts, phone cases, etc.

The image in question that was used is this one:

If you see this image in any shape or form being sold on merchandise, please do not buy from the seller. I did not give consent for this drawing to be used in sales, and I personally have not made any merchandise with this design as well.

I've sent an email to TeePublic's Legal team but haven't heard back and it's been a week. I've also just sent a support ticket, so hopefully that reaches them and they'll remove the design from their site. If anyone has ever had any experience with this, I'd love to hear how it got resolved on your end! This is the first time I've ever had my art stolen, and it really sucks...

Looking through the thief's gallery, it looks like a lot (if not all) designs on their store is stolen artwork as well. I'll link their storefront below just in case you find your designs being used and need to contact TeePublic's Legal team as well, but please do not harass this person. Just report them to TeePublic and have them resolve this issue.
